Description

You are bidding on a small sample with a very sharp crystal of rare jeanbandyite on sulfide matrix from the best locality for the species. Comes with original index card but I could not locate the original slide taken by Dan. Still a fantastic example of this rare mineral. 

This sample is from the collection of Dan Behnke, long-time friend, micromounter and prodigious photographer. I am pleased to be able to offer selections from his large collection, many of which are illustrated specimens in Rocks & Minerals, The Mineralogiocal Record, Photo Atlas of Minerals and many other publications. All samples from his meticulously catalogued collection will come with his original index card with all notes, photography annotations and other pertinent information, as well as any slides Dan may have taken of the sample with publication notes and date the photo was made.
